Crossovers That Should Be: Legends Dabon

[Necratoid]

The hard parts would be that she'd be screwed up from the time before those two took over, the damage that them keepng a clan head's daughter as a ward (its not like they don't know were she came from),  and keeping Hinata Hinata-like what with her being raised by a possibly crazy rapping demon container... for one thing I'm seeing her as being the little sister of two demon containers and not actually being as cowed.
Ignoring plugging the hole in team 8... it would be an act of naked aggression and mocking/taunting for a Kage to be keeping the daughter of someone so prominent as a ward... I'm thinking at least an extra war in there, probably the Hyunga being Itachi bait as they aren't allowed to actually retrieve her by force.  Hinata's dad does have a large force of troops that can be ordered to go for it on pain of melting brains... and pain.
Its likely that that clan verses village war could actually be what gets the old Lightning Kage killed/deposed.  There may simply not be enough of a clan to raise her... which means that Hinata is being trained/raised as a an apologe thing.
If Uchiha also fall the landscape is going to be unrecognizable and leave Negi in an ugly spot of an avenger without a real target... he shouldn't be sealed by this point.
